The Advantage of our Precast Highway Grids

The Advantage of our Precast Highway Grids

Our Precast Highway grids are supplied throughout the UK. Triangle is the first company in the UK, and possibly the only company in the world, supplying Precast Highway Grids.


The advantages:
  • The Precast Concrete Base sections each weigh in at 9T, to cover any road width from 3 − 8 metres.
  • The grid can be installed in 5 days (from excavation to completion), compared with the highly disruptive conventional cast-in-situ grids requiring 4 − 6week road closures and diversions.
  • The steel is hot dip galvanised and is very Heavy Duty − the carrier beams are 25mm plate and the transverse beam box sections are 6mm thick.
  • The grid anchors are cast into the Precast Bases − substantially stronger and no site drilling is required!
  • All the steel bases are secured to the anchors using specialist locknuts, as used by Network Rail.
  • Complete Highway side fencing kits are supplied with each grid.
  • The grids are tested to hold 150T.

So, for an example, a 6m grid will have a combined base weight of 27T. With 4.6T steels and comparing that to our competitors steels weighing in at approx. 2T, the weight difference proves that our grids are truly made to last and are in fact, super heavy duty.

All our grids are quick to install, cost effective and low maintenance.

They are CE Certified to BS4008:2006 and BS EN 1991-2 Part 2 Euro Coding.
